Description

A kind of novel solid round steel tube cutting die

Technical field

The utility model relates to machined field, is specially a kind of novel solid round steel tube cutting die.

Background technology

In machining process, often need to process pipe fitting, wherein, just comprise the cutting processing to solid round steel.In general, prior art is all to adopt sawing or die-cut mode to process to the cutting processing of the original paper of the solid round steel of this class, special construction due to solid round steel itself, adopt the technology mode of sawing quite time-consuming, and need to polish and could normally use at section after cut-out, and the wearing and tearing of saw blade are very serious, processing cost is higher; And adopt the mode of Punching Technology can effectively improve working (machining) efficiency, and the cutting section of pipe is comparatively smooth, but, under traditional Punching Technology mode, do not adopt mould or just adopt simple jig to assist, its section can produce slippage to a certain degree, and the angle of collapsing cutting out is very large, and jagged after blanking.

And along with progress and the requirement to retrofit equipment of modern crafts, some for installation requirement and the higher device of dimensional requirement on, still be difficult to meet process and assemble requirement, make the pipe fitting of the slippage of this section still belong to substandard product, still need to cut section at it and polish.Thereby need to improve to meet the disconnect request under its high manufacturing accuracy to existing mold.

Utility model content

The technical problem that the utility model solves is to provide a kind of novel solid round steel tube cutting die, to solve the shortcoming in above-mentioned background technology.

The technical problem that the utility model solves realizes by the following technical solutions:

A kind of novel solid round steel tube cutting die, comprise patrix and counterdie, wherein, patrix is mobile mould, on it, by die shank, is connected with lathe, on described patrix lower surface, by fixture, is connected with a slide track seat, this slide track seat is that two steel construction substrates form, and the slideway consisting of these two steel construction substrates is three stage structures, its top is linear ramp, and in the bottom of this linear ramp, is connected with two bending slideways continuous and opposite direction; And described counterdie is fixed in the machining position of lathe for spacing, on it, be provided with a planar sliding shoe for left and right slippage, the top of this sliding shoe is that tangent plane is the rod structure of orthohexagonal horizontal placement, centre position has manhole, and the cut-out of perforate is inserted in the middle of position with pores is embedded with one, described cut-out is inserted rear portion for cutting off pedestal, and the outside dimension of the big or small and to be processed round steel of this cut-out middle perforate of inserting is consistent.

In the utility model, the width at the width position place of the width of the slideway in the middle of described slide track seat and sliding shoe is consistent, and leaves allowance.

In the utility model, the knuckle position in described slide track seat between two continuous bending slideways is 5 ~ 6mm with respect to the horizontal sliding distance of slideway bottom starting point.

In the utility model, described cut-out is inserted and is made for high strength alloy steel, and can on the aperture of manhole, carry out workpiece replacement.

In the utility model, the left and right slippage of described sliding shoe realizes on a wear-resisting backing plate, and has staggered oil circuit groove on this wear-resisting backing plate, the slippage for auxiliary sliding shoe in process.

Beneficial effect: stamping die of the present utility model can be directly die-cut on stamping machine, it utilizes the slideway structure on three rank that a traditional stamping-out punching press is become to two step stamping-outs, and in this die process, in closing course, utilize two continuous bending slideways from a side subpunch 5-6mm, and then cut off from opposite side punching press, can effectively solve the problem that production efficiency is low, cutting section is neatly clean simultaneously, without burr and the appearance qualities such as angle that collapse.

Accompanying drawing explanation

Fig. 1 is the schematic diagram of the utility model preferred embodiment.

The specific embodiment

For technological means, creation characteristic that the utility model is realized, reach object and effect is easy to understand, below in conjunction with concrete diagram, further set forth the utility model.

Preferred embodiment referring to a kind of novel solid round steel tube cutting die of Fig. 1, in the present embodiment, comprise patrix 1 and counterdie 9, on wherein said patrix 1, by two steel construction substrates 3, form slide track seat, one, left side lower inside in these two steel construction substrates 3 forms a leg-of-mutton cushion block, another piece has the consistent groove of a size and size and triangle cushion block on the position of triangle cushion block symmetry therewith, make the slideway in slide track seat be shaped to three stage structures, its top is linear ramp, and in the bottom of this linear ramp, be connected with two continuously and the bending slideway of opposite direction, knuckle position between two bending slideways is 5mm with respect to the horizontal sliding distance of slideway bottom starting point.And in counterdie 9 parts, comprise a wearing plate 7 and the fixing back of the body piece 8 of wearing plate 7, on this wearing plate 7, have staggered oil circuit groove, on wearing plate 7, be provided with a sliding shoe 4, the top of this sliding shoe 4 is that tangent plane is the rod structure that regular hexagon is laterally placed, centre position has manhole, and the cut-out of perforate inserts 5 in the middle of position with pores is embedded with one, cut-out is inserted 5 rear portions for cutting off pedestal, and the insert outside dimension of the big or small and to be processed round steel of 5 middle perforate of this cut-out is consistent.
